Salting the glass: Rub lime wedge around rim of martini or margarita glass to wet it. Dip glass in pile of salt at a slight angle, and rotate until you have fully coated the rim. (You can skip this step if you are watching your sodium intake or simply don’t like the salt; or replace the salt with sugar for an extra-sweet treat.)

Fill a shaker with ice.

Add tequila, Curacao, and lime juice (fresh is best—use the same lime you used to salt the glass).

Shake for 8-10 seconds.

Strain into martini glass.

Garnish with lime wheel (slice).
